Overbuilt AVR That Pushes Kef R3s Well
This AV receiver is considered seriously overbuilt for its price point, with best-in-class SINAD for the main three channels. It drives Kef R3 speakers very well. For music, Tidal is preferred over Spotify, and using the music option is recommended. When connected to a PC, Windows exclusive mode is suggested for movies, which automatically sets the receiver to Dolby listening modes; the output should match or exceed physical channels. Denon's 3800h is not recommended, while the 4800h is; Marantz units are described as heavily flavored by their DACs.
Pros
- + overbuilt for its price point
- + best-in-class SINAD for main three channels
- + pushes Kef R3 speakers very well
Cons
- − Spotify is bad for music

Serious firmware issues cut video and audio
The new Onkyo RZ series has a serious firmware update problem that causes video and audio to cut out constantly, along with handshake signal loss when switching inputs. After updating the firmware, the RZ50 began showing these issues, and a replacement RZ70 did the same. The problems did not go away, prompting a switch to another brand after more than 15 years of using Onkyo. The previous Onkyo model had a solid build, and the goal was to upgrade to 8K.
Pros
- + Previous Onkyo model had a solid build
Cons
- − Firmware update causes video and audio to cut out
- − Handshake signal loss when changing input
- − Problems persist after firmware update

Powerful sound and features, with rare audio glitches
This receiver delivers impressive sound in a 7.2 setup and has no video issues. Its room calibration is more complicated than Audyssey but offers finer tuning. The mobile app works well. Occasionally, on power-up there is no sound and the unit must be unplugged and replugged, which also resets the calibration feature; this has happened about three times over months of use. Streaming audio is less convenient than with some other brands. Overall, it is a satisfying choice for the price.
Pros
- + powerful sound
- + no video issues
- + fine tuning better than Audyssey
- + works well with mobile app
- + good value
Cons
- − calibration setup more complicated
- − rare no-sound issue requiring power cycle
- − streaming audio less convenient than some competitors
